Flexible element comprising a variable number of flexible bushes, depending on the torque to be transmitted.
1 Inner with tapped or smooth holes (normal mounting or on fly wheel).
2 Precompressed natural rubber bonded to inner 1 and to outer the half-cylinders 3.
3 Half-cylinders bonded to the rubber.
4 Outer housing ensuring precompression of rubber by exerting pressure on the half-cylinders 3.
Steel disks:
5 Flange to which the inner studs are attached (normal mounting).
6 Disk to which the studs are attached (flywheel mounting).
Die cast steel hubs:
7 The two hubs are identical. They may be bolted to disks 5 or 6 depending on the mounting used.
The AXOFLEX coupling is designed with the following features:
– Radial disassembly without moving the machines that are coupled (usually very large machines).
– Precompression of the rubber which limits operation under tension.
Advantages:
Good axial flexibility which allows great axial displacement, for example in the case of conical rotor machines.
Flexible element:
1 Six fairly hard natural rubber shaped support blocks, on the inside edge of the outer ring of the coupling.
Flange:
2 inside flange has six arms which fit axially between the blocks by “blind axial” assembly.
Outer ring:
3 Ring with teeth that hold the blocks.
Standard SAE fixing and centring.
Flexible element 1: polyurethane in the form of a Maltese cross.
Flange 2: cast iron with drive segments 3 supplied unbored (except633054 and 633055).
Variations : For assemblies with a ring or spacer, consult our technical manuals.
Flexible element comprising:
1 Natural rubber in the form of a cross.
2 A floating aluminium or steel star, whose arms are bonded to the rubber.
Mountings:
Two aluminium bosses, bonded to the rubber which will be attached to one of the machines.
Two bosses bonded to the rubber which will be attached to the other machine.
Flexible element:
1 Metallic bobbins linked together by rayon fibres.
2 The whole unit 1 is potted in natural rubber and is hexagonal.
Flange:
3 Forged steel specially bored to accommodate the separate hub.
4 Universal separate hub (not supplied by PAULSTRA).
